The five core attributes in Vuex are: state, getters, mutations, actions, modules.
Let’s take a look at these five attributes.
state: basic data of vuex, used to store variables
geeter: data derived from basic data (state), equivalent to the calculated attribute of state
mutation: Submit The method of updating data must be synchronous (if you need to use action asynchronously). Each mutation has a string event type (type) and a callback function (handler).
The callback function is where we actually change the state, and it will accept state as the first parameter and submit the payload as the second parameter.
Action: The function is roughly the same as mutation. The difference is ==》1. Action submits a mutation instead of directly changing the state. 2. Action can contain any asynchronous operation.
modules: Modular vuex allows each module to have its own state, mutation, action, and getters, making the structure very clear and easy to manage.
